Abstract

The first luminescent twelve-nuclear rhenium cluster complexes were obtained. Three new clusters, namely, [Re₁₂CS₁₄(μ-Cl)₃Cl₆]^5-, [Re₁₂CS₁₄(μ-Br)₃Cl₆]^5- and [Re₁₂CS₁₄(μ-Br)₃Br₆]^5-, were synthesized using the non-isovalent substitution of μ-O ligands within the {Re₁₂CS₁₄(μ-O)₃}⁰ cluster core by halide anions. The geometry of the new clusters was investigated by X-ray structural analysis, and the electronic structures were evaluated by the use of DFT calculations. It was found that compounds based on these anions showed red luminescence in both the solid state and solution that was never observed before for previously studied twelve-nuclear rhenium clusters.
